Fullstack Engineer & Entrepreneur
I build products end to end — from planning and engineering to launch and sales. Part entrepreneur, part fullstack engineer.Warsaw / Remote · EST-friendly
I build products end to end — from the first plan to the last sale, and all the engineering in between.
I'm a fullstack engineer and entrepreneur with 6+ years building production web apps in FinTech, e-commerce, travel, and SaaS. I work across the whole product — planning and strategy, design, engineering, launch, and sales.
My main stack is React, Node.js, and TypeScript. I focus on frontend architecture and AI/LLM features, plus the infrastructure to run them in production — Docker, CI/CD, Coolify, AWS.
